Fellow RFI hunters,
My latest source is s8-s9 nearly across the hf bands on my vintage
TS830s and Doublet. I use the 830s mainly as a station reference when
hunting RFI. I have triangulated it to a single phase 7.2kv pole */3
houses away./* Unable to hear it with Ultrasonic dish, although about
1/3 of the side of the pole is inaccessible due to a very jungle like
backyard (bad renters moved out, owner died, house recently sold, long
story).
It just has a insulator at top for single phase, pole pig fed by a short
wire from the single phase, then lower 3 wires I am assuming lower
voltages, neutral, ground, and 3 house drops.
Ive been looking at some pictures I took.
The stapled ground wire on the wood pole goes up to with maybe 2 inches
of the 2 bolt metal bracket holding the top insulator on but does not
appear to be connected. I can zoom in on the picture and see this.
So, does this strong an arc just about have to be on that insulator area
of the 7.2kv or am I wrong and it can be in the ground system, 220v run,
etc?
More detail here;

I emailed the Utility this past Thursday about this one and another
close by that I am hearing with the Ultrasonic.
